""A seat track consists of 2 parts. Once connected to the vehicle, the other to the physical seat. The 2 tracks join together. My seat track had so much play in the track that when I turned right or left, the entire seat shifted in it's own track. Very unsecure. Most notably, I had 3 seats tracks replaced in my 1996 Yukon which indicates GM is using the same faulty part supplier as they did 30 years ago.""
